To all whom it mag concern:

Be it known that I, CAMI'LLE J IiAN HAU- TIER, citizen of'the Republic of France,"resident of 53 Rue du Chateau, Boulogne su Seine, Seine, in the saidRepublic, engineer, have invented certain new and useful Iniprovements in Internal Combustion En; gines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others. skilled in the art'to which it appertains to make and use the same, reference being had to the accompanying drawings, and to let ters or figures of reference marked thereon, whichform a part of this specification. I

This invention relates'to distributing devices for internal combustion engines and consists in using a singledistributer moved parallel to theaxis of'the cylinder and having ducts adapted to cooperate with suitable ports in the wall of the cylinder between'the two ends of the stroke of the piston, so as tof admit into the cylinder at each suction stroke a charge of fresh gas and at the same time a complementary and variable proportion of burnt gases in order that the volume admitted into the cylinder may be kept always? constant whatever the quantity of "the fresh gas admitted, and in order that the ignition' of this fresh gas may be 'facilitated'by rea son of the temperature which it acquires from the hot gases wherewith it is intimately mixed. The distributer consists of a cylindrical slide having rectilinear movement and renderedtight by packing rings, the width of which is proportional to the stroke of the slide; it is mounted so thatits axis does not cut the axis of its controlling shaft, so that:

at periods corresponding with the compres-r' sion, explosion and the greater part of the expansion, the exhaust port is completely covered by the corresponding packing ring;

The method of distribution is applicable both to four-stroke, cycle and to two stroke cycle internal combustion enginesfthe 'con-' trolling shaft of the distributing slide being driven in the first case at half thefspeed of the crankshaft and in the secondca'seiat the same speed as this shaft.

The accompanying drawing shows by way? of example inFigures 1 4i diagrammatic sections through'the'axis of the workingcyle ind'er of a four-stroke internal combustion". engine having ;(l s ributer according to; the

invention;

attthe beginning of the compression stroke and at thebe'ginning ofthe working stroke respectively; Fig. 4 shows the 'distributer slide displaced relativelyjto the Working piston which is in an intermediate position so as to increaseithe proportion of' burnt gases which sucked" back into the cylinder, thereby diminishing the quantity of fresh parts at the beginning ofthe suction stroke, i

gas admitted. Fig. 5 {is a side elevation,

partly diagrammatic and drawn' to j an en--' larged scale of the sleeve'which when shifted on the distributing shaft determines the 1 displacement of the distributing slide.

The working cylinder a," in -wl1icl1 moves the piston 'b,-. is provided with two lateral portsfc and (Z adapted respectively for the admission a'ndthe exhaust and situated betwee'nthe'two ends of thestroke of the pis ton b, the admission port 0" being forfeXam-' pleas shown in thedrawing at two-thirds "of the stroke of the piston. e is the'cranksh'aft' and f a connecting rod between the pistonb I and this shaft. l V

At that side'ofthe cylinder a in which the ports cand d 'ar'e'situated there is a cylindrical guide 9 for the distributing slide. The,

latter is an open ended cylinder subdivided internallyby two partitions', j; the chamber between these partitions'has lateral admission portsk; intended to register with the? admission port c of cylinder 0;. Above the upper partition 2' the cylindrical slide has a lateral port Z intended to register'with'the port 65 of the cylinder a so as to putthe latter into communication fwithj the j exhaust through pipem which forms aneexte'nsion of the cylindrical guide g. The admission duct n for fresh gas'opens into the cylindrical guide 9 at a, point substantially in line with, the admissionport c'of cylinder- 1a. Thedis tributing slide is rendered tight by packing rings 0 of considerable width whichlslide in contact with the admission and exhaust.

pturning atone half thespeed' of the cranlr 1 shafte' with'which 'i'ti's in" gear through a1 suitable train 51,-: the ,79 isf mounted with its'axis'out of theaxial line of the dis-1 tributing' slide and a connecting rod? 'conf nect's it with 1 the slideif 'n' hi axial ei hteenth-the movement of" the slide 'is not uniformbut is sleeve has a rectilinear groove t engaging a straight'feather .u on the portion 29 of-the shaftaand' a helical groove 4) engaging a feather oflike form w on the portion 79' of the'shaft. By means of a collar at on the sleeve .9 the latter can be easily displaced. Itjwill be seen that axial movement of the sleeve on the shaft will rotate part 39 there of relatively to part 7), thus changing the angular position of the distributer shaft with respect to the motor shaft and displacing thedistributer slide it relatively to the working piston b.

The arrangement'operates as follows When piston Z) is at the upper end of its stroke as shown in. Fig. 1, and is about to descend to perform the suction stroke, the admission and exhaust ports 0 and (Z of the cylinder are closed by the packing rings 0 of the downwardly moving distributing slide. As the piston and distributer continue their downstroke the lower packing ringof the distributer uncovers the admission port 0 and owing to the slower movement of the distributer fresh gas is drawn into the cylinder through a andZc-from the time the piston uncovers the port 0 until the piston reaches the end of its down stroke,

as shown in Fig. 2.

When the piston begins the compression stroke, the ports 0, is, n, are in register, and a part of gas drawn in on the suction stroke is returned through the admission port 0, which remains open so that only the charge remaining between this port and the end of the cylinder constitutes the maximum volume of fresh gas taken into the cylinder. hen the piston covers the port 0 the fresh gases are compressed asshown in Fig. 3. At the moment of the explosion the packingrings 0 and the piston Z) cover com pletely the ports 0 and (Z as well as during the whole period which precedes the'advanced exhaust.

the motor shaft 5, said port Z, remains more orlless in registration withport 0? during a part of'this period. The VOlIlHlGZLClIIllttBd consists only in part of the fresh gases,

being completed by thehot burnt gases so that the-compression remains constant and combustion is facilitated and more complete. T claim 1. In "an internal combustion engine, I a
